Datatype: SPT

The spectral classification is basically separated in two datatypes
HD-like spectral types
The one-dimensional Harvard spectral type (in the HD form) are collected under the datatype spt
This datatype also collects the photmetric quantification done mainly in the near-infrared for late-type stars

The MKK classification
It refers to the usual MK bidimensional classification. The datatype is named mkk

Selected MK types
When many classifications exist in a cluster, a selection one the authors has been performed to keep only one type per star. Therefore, a variant has been introduced and this datatype is named mks.
